Sugar Baby Blues? Sugar Maple Regeneration in NH with Dr. Natalie Cleavitt, part of "Cold is Cool" series

Join Cornell University Research Associate Natalie Cleavitt to learn about New Hampshire’s sugar maples and their ability to regenerate successfully in our changing forests.   

Sugar maples are one of New Hampshire’s most important tree species, whether you look at this from an economic, environmental, or cultural perspective.  They drive our fall foliage tourism industry, power state-wide syrup production, provide high-quality timber, and are a key ecological component of our northern hardwood forests.   Long term research on sugar maples at Hubbard Brook Experimental Forest in Woodstock, NH has uncovered a significant decline in sugar maple regeneration success over the past 30 years.  Seedling sugar maples are having difficulty surviving, which is likely due to a combination of factors including soil acidification, winter weather pattern changes due to climate warming, and increased competition with other tree species.  A new community science project began in 2018 to help determine whether the sugar maple regeneration failure seen at Hubbard Brook is happening throughout New Hampshire.  Four Forest Society forest reservations are study sites for this project.

Join Natalie Cleavitt, lead scientist on the Sugar Maple Regeneration Community Science Project (SMRCSP) as she explains why sugar maple regeneration may be threatened in our state, what she has learned at Hubbard Brook Experimental Forest, and what the early data from the community science project looks like.  We welcome your questions about sugar maples and forest dynamics, and hope you’ll come away with a greater understanding of the challenges facing one of our most iconic New Hampshire trees.
